3F UL Gear Bivy Footbox - UHMWPE Grid Nylon

Many experienced hikers put a jacket over the foot of their sleeping bag to keep condensation off. The 3F UL Gear Bivy Footbox does the job instead, for only 60g.

This UHMWPE grid version is taped inside and fully waterproof, so it also works as an extra waterproof liner for your sleeping bag compression sack.
